Lincoln, Leicester and Northampton reached 4,479,578 tons. Thus, although the production of the Cleveland district has fallen since 1880, the total production of the lean ores from this geological horizon has increased from 9,0.26,000 to 10,157,138 tons. Estimating the average iron content of the ore at 32 per cent, and the iron in the pig at 93 per cent., this amount of ore represents ahout 3,500,000 tons of pig-iron, or about 40 per cent, of the total pig-iron made in the kingdom. Tahles XXIII-V and W give statistics on the iron industry of this district.
